If \(\vec{a} = 4\hat{j}\) and \(\vec{b} = 3\hat{j} + 4\hat{k}\), then the vector form of the component of \(\vec{a}\) along \(\vec{b}\) is

A. \(\dfrac{12}{10\sqrt{3}}(3\hat{j}+4\hat{k})\)
B. \(\dfrac{12}{5}(3\hat{j}+4\hat{k})\)
C. \(\dfrac{12}{\sqrt{13}}(3\hat{j}+4\hat{k})\)
D. \((3\hat{j}+4\hat{k})\)
Answer» C. \(\dfrac{12}{\sqrt{13}}(3\hat{j}+4\hat{k})\)
